Anyone have a Benwil TP-9 or TP-7, 2-post lift?

Anyone have a Benwil TP-9 or TP-7, 2-post lift?
My TP-9 is missing the original Base.
The base is used as a template for setting up.
I need to know the width apart from the back side of each column.
Original manual shows 144-3/4" for the tabs at the outside edge of the base.
But I do not know how long those tabs are.
Since this lift uses chains I have less leeway for error.
I know this is really reaching, but they sold a lot of these and I could use some good luck.
